In the last 2 weeks I:

- reverse-engineered a Mac App Store app, modernized its UI, and added support for Apple Silicon. It took about 90 minutes running in the background.

- created faithful macOS ports of ~7 classic 68k Macintosh games; most are now written in Swift, with MacToolbox routines reimplemented (one exception: MS Flight Simulator 1.02 worked better as a plain C app, since it had a hand-authored bytecode interpreter in 68k assembly)

All it takes is a goal with nearly 100% specificity
